The 74VCXH16244 is a low voltage (1.2V to 3.6V) VCC 16-bit buffer/line driver with 3-STATE outputs, designed for high speed operation while maintaining low CMOS power dissipation. The device is nibble (4-bit) controlled and features active bushold circuitry, eliminating the need for external pull-up resistors to hold unused or floating data inputs at a valid logic level.
The 74VCXH16244 contains sixteen non‑inverting buffers with 3‑STATE outputs, organized as four independent 4‑bit nibble groups. Each nibble has its own control inputs, and all control pins can be shorted for full 16‑bit operation. The device includes active bus‑hold circuitry on the data inputs, eliminating the need for external pull‑up resistors.
The datasheet provides absolute maximum ratings, recommended operating conditions, DC and AC electrical characteristics, propagation delay, capacitance values, and package dimensions for both FBGA and TSSOP options. It also lists ordering codes and notes on life‑support usage restrictions.
